The invention relates to a turbine ring assembly for a gas turbine, that comprises a full ring (10) made of a single piece and of a composite material having a ceramic matrix, a metal structure for holding the CMC ring including metal annular holders (20, 30) between which the CMC ring is provided while allowing for a differential expansion at least in the radial direction between the CMC ring and the annular holders, a means (40-42) for centring the CMC ring, and at least one member for rotatingly blocking the CMC ring about the axis thereof.
Un ensemble d'anneau de turbine d'une turbine à gaz, comprend un anneau complet (10) en une seule pièce en matériau composite à matrice céramique (CMC), une structure métallique de support de l'anneau en CMC comportant des supports annulaires métalliques (20, 30) entre lesquels l'anneau en CMC est disposé tout en permettant une dilatation différentielle au moins en direction radiale entre l'anneau en CMC et les supports annulaires, des moyens (40-42) de centrage de l'anneau en CMC, et au moins un élément de blocage de l'anneau en CMC en rotation autour de son axe.
